    Motivated by Watson’s lemma (§2.3(ii)), we substitute (2.6.2) in (2.6.1), and integrate term by term. …Inserting (2.6.2) into (2.6.1) and integrating formally term-by-term, we obtain … The Stieltjes transform of f ( t ) is defined by … On substituting (2.6.15) into (2.6.26) and interchanging the order of integration, the right-hand side of (2.6.26) becomes … In terms of the convolution product

    Assume that a , m , and n are integers such that n > a , m > 0 , and f ( 2 m ) ( x ) is absolutely integrable over [ a , n ] . Then … This identity can be used to find asymptotic approximations for large n when the factor v j changes slowly with j , and u j is oscillatory; compare the approximation of Fourier integrals by integration by parts in §2.3(i). …

    On the circle | z | = r , the function f ( z ) - g ( z ) has a finite number of singularities, and at each singularity z j , say,

    2.10.30 f ( z ) - g ( z ) = O ( ( z - z j ) σ j - 1 ) , z z j ,

    where σ j is a positive constant.

  • In these circumstances the integrals in (2.10.28) are integrable by parts m times, yielding …
